- a plurality of lower support columns 400-5 is provided on the upper surface of the lower plate 400-1 while being spaced out at regular intervals, with a bore 400-3 having a predetermined length formed through a center of each of the lower support columns 400-5 to contain a shock-absorbing member 400-7 therein.
- the shock-absorbing member 400-7 which is contained in the bore 400-3 of each of the lower support columns 400-5 performs the shock-absorbing function to protect the players from injury when the players apply pressure to an upper plate 400-11.
- a plurality of longitudinal lower reinforcing ribs 400-9 having a predetermined length protrudes upwards on the upper surface of the lower plate 400-1 at positions between the lower support columns 400-5, thus supporting the lower plate 400- 1 and guiding water drained from a plurality of drainage holes 400-15 of the upper plate 400-11 so as to drain the water.
- the upper plate 400-11 is placed above the upper surface of the lower plate 400-1 to drain rainwater and irrigation water.
- a plurality of water guide grooves 4OOIS having a predetermined length is formed on the upper surface of the upper plate 400-11 to define a lattice pattern, thus guiding the rainwater and the irrigation water to the drainage holes 400-15 to allow the water to drain smoothly.
- the drainage holes 400-15 are formed through the upper plate 400-11 at positions along the water guide grooves 400-13 while being spaced out at regular intervals, thus draining the water guided by the water guide grooves 400-13 to the lower plate 400-1.
- a plurality of upper support columns 400-17 is provided on the lower surface of the upper plate 400-11 while being spaced out at regular intervals, with a bore 400-21 (see FIG. 4A) having a predetermined length formed through a center of each of the upper support columns 400-17 to receive therein each of the lower support columns 400-5 containing the shock- absorbing member 400-7.
- the shock-absorbing and drainage layer 400 further comprises a plurality of longitudinal upper reinforcing ribs 400-19 having a predetermined length and protruding downwards on the lower surface of the upper plate 400-11 at positions between the upper support columns 400-17, thus supporting the upper plate 400-11.
- the shock-absorbing members In the surface structure, the shock-absorbing members
- the surface structure for athletic fields having the above-mentioned construction according to the present invention is built on an athletic field as follows . First, a plurality of underdrains 100 is formed in the ground at positions spaced out at regular intervals, and thereafter, the freezing prevention layer 200 is spread on the ground.
- the pebbled subsurface layer 300 is spread on the upper surface of the freezing prevention layer 200.
- the shock-absorbing and drainage layer 400 to drain rainwater and irrigation water and perform a shock- absorbing function to protect players is placed on the upper surface of the pebbled subsurface layer 300.
- the process of placing the shock- absorbing and drainage layer 400 on the pebbled subsurface layer 300 will be described in detail herein below.
- the lower plate 400-1 of the shock-absorbing and drainage layer 400 having the lower support columns 400-5 is placed on the upper surface of the subsurface layer 300 which acts as a junction material.
- the shock-absorbing members 400-7 are inserted into the bores 400-3 of the lower support columns 400-5.
- the shock-absorbing members 400-7 comprise two types of members with different heights, which are alternately arranged on the lower plate 400-1 while being contained in the bores 400-3. Thereafter, the upper plate 400-11 is placed on the lower plate 400-1. In that case, as shown in FIG. 4A, the upper support columns 400-17 formed on the lower surface of the upper plate 400-11 are aligned with the lower support columns 400-5 formed on the upper surface of the lower plate 400-1. When the upper plate 400-11 is pressed downwards, the lower support columns 400-5 having the shock-absorbing members 400-7 are inserted into the bores 400-21 of the upper support columns 400-17 as shown in FIG. 4B.
- each of the lower support columns 400-5 is designed to be slightly smaller than the inner diameter of the bore 400-21 of each of the upper support columns 400-17.
- the lower support columns 400-5 are smoothly inserted into the bores 400-21 of the upper support columns 400-17 and the assembled state of the lower and upper support columns 400- 5 and 400-17 is maintained regardless of thermal expansion and contraction of the columns 400-5 and 400-17 according to variation in atmospheric temperature.
- the shock-absorbing members 400-7 having the higher height are in contact with the lower surface of the upper plate 400-11, while the shock-absorbing members 400-7 having the lower height are not in contact with the lower surface of the upper plate 400-11.
- the operational effect of the shock-absorbing and drainage layer placed on the pebbled subsurface layer will be described herein below.
- the water flows to the drainage holes 400-15 through the water guide grooves 400-13.
- the drainage holes 400-15 drain water to the lower plate 400-1.
- the water drained to the lower plate 400-1 flows along the longitudinal lower reinforcing ribs 400-9 to the subsurface layer 300 and the freezing prevention layer 200 which are sequentially placed under the lower plate 400-1. Thereafter, the water drains to a sewer through the underdrains 100.
- the upper plate 400-11 applies pressure to the lower plate 400-1.
- the lower support columns 400-5 of the lower plate 400-1 having the shock-absorbing members 400-7 are further inserted into the bores 400-21 of the upper support columns 400-17 of the upper plate 400-11 while compressing the shock-absorbing members 400-7. Therefore, impact which may be applied from the shock-absorbing and drainage layer 400 to the player can be distributed and absorbed by the shock-absorbing members 400-7. Furthermore, because the shock-absorbing members 400- 7 with different heights are alternately arranged in the bores 400-3 on the lower plate 400-1, the shock-absorbing members 400-7 absorb the impact in a stepwise manner.
- the present invention provides a surface structure for athletic fields, which has desired elasticity and permeability, thus performing a shock- absorbing function and a drainage function at the same time. Furthermore, the shock-absorbing operation of the surface structure for athletic fields is executed in a stepwise manner, so that the surface structure protects players from injury. In addition, as the shock-absorbing and drainage layer is made of hard plastic materials, thus having desired durability and desired load support ability.
